Biology on Poseidon’s end

Biology on Poseidon’s end - 2
- Event Based
- Order is important
- Reactive
Simple get biomass

OSMOSE get biomass

Object Oriented Fishing
- Where the fish is?
- Fish movement/growth?
- Events modifying LocalBiology
- Or entirely exogenous
- What decides how many catches?
Object Oriented Fishing

Simple React

OSMOSE React

Slices
- Build a model not a cake
- Sources of opacity
- Slices
- Simplest geography, biology, fishery
- Iteratively make complex
MSC prices for size incentives
- Change in market prices
- Change in hold size information
- Inference overhaul
MSC prices for size incentives - 2

Delays in licensing
- Very little new code
- Results may be obvious
Delays in licensing - 2

Delays in licensing - 3

Delays in licensing - 4

Delays in unloading fish
- Easy as long as we know its effect on sale prices
- Results may be obvious
Adaptive Effort Regulations
- Straighforward application of Reinforcement Learning
- Might start initially with some pre-made rules
- Might be only partially enforced
Adaptive Effort Regulations - 2

Partial Spatial Effort Regulation
- Very similar to what we have already
- Might be hard to make adaptive
Partial Spatial Effort Regulation - 2
Opt-in Gear
- Easy to implement
- Hard to get transition speed right
Opt-in Gear - 2

Market Concentration
- Completely separate model ?
- Can we just grab some IO model?
Cheating/Different regimes
Fishers

Change Base
- Moving as a discrete choice : easy
- Long-term building of new ports: hard
Translocation
- ‘Threshold’ translocation is easy to add
- Might be too “effective” without much gear noise
Discarding
- Already coded in terms of weight
- Needs to be made size/age specific
Entry - Exit
- Easy to implement
- Hard to get transition speed right
- Usually very strong effects
Habitat Damage
- Easy to implement
- Needs good feedback loop into the biology layer
Age/Length Structure
- Already in
- Missing habitat effects
- Missing predator/prey effects
Depth Layers
- Major work
- Easier on the decision side
- Hard on visualization
- Harder on the biology side
